A rodent trap includes a pivotally mounted jaw which snaps to a closed position to enclose a rodent when activated by a rodent attempting to free itself from an adhesive coated removable trigger member. The trigger member and the rodent can be easily removed from the trap. The trigger member can be replaced with a new trigger member and the trap can be reset and reused.

The present application claims priority from Provisional Patent Application Ser. No. 61/150,892, filed on Feb. 9, 2009, entitled “Rodent Trap With Removable Trigger Plate.”
The present invention relates generally to the field of rodent traps and more particularly, to a rodent trap with a removable trigger plate.
The prior art related to rodent control includes various examples in which bait is placed on a trigger plate to attract a rodent. Movement of the trigger plate by a rodent causes a spring loaded member to trap the rodent. In prior art traps, after the trap has been activated, the user disposes of the trap along with the rodent. The need to dispose of the trap after a one-time use is both costly and inconvenient for professional sanitarians who typically utilize a large number of traps in order to clear rodents from a large industrial facility.
Another problem found in prior art rodent traps is related to the situation in which the bait which has been placed on the trigger plate is often removed from the trap by a rodent without activation of the trap. This renders the trap useless for rodent removal.
The above problems are clearly evidenced in a typical prior art rodent trap such as the trap shown in U.S. Pat. No. 6,415,544 to Leyerle, et al, for “Rodent Trap With Entrapping Teeth.” In this trap, the entire trap is disposed of along with the entrapped rodent.
It is an object of the present invention to provide a rodent trap with a removable trigger plate in which the possibility of removing the bait without activating the trap is significantly reduced.
Another object of the present invention is to provide a rodent trap with a removable trigger plate in which the removable trigger plate facilitates continued reuse of the trap.
Another object of the present invention is to provide a rodent trap with a removable trigger plate which includes an adhesive layer which ensures that motion of the rodent attempting to escape from the trap is transferred to the trap and ensures activation of the trap.
Another object of the present invention is to provide a rodent trap with a removable trigger plate which includes an early removable and replaceable member having an adhesive layer.
Yet another object of the present invention is to provide a rodent trap with a removable trigger plate which includes a relatively small number of component parts which can be manufactured economically in volume resulting in a relatively low unit cost.
Other objects and a more complete understanding of the present invention will be made clear hereinafter.
In accordance with the present invention, there is provided a rodent trap with a removable trigger plate which includes a pivotally mounted jaw which snaps to a closed position to enclose a rodent when activated by the rodent attempting to free itself from an adhesive coated removable trigger. The trigger plate and the rodent can be easily removed from the trap. The trigger plate can be easily replaced with a like trigger plate and the trap can be reset and reused.
In an alternative embodiment of the present invention, the trigger includes a removable member which has an adhesive layer. The removable member and the rodent can be easily replaced with a like member and the trap can be reset and reused.
Additional objects, features and advantages of the invention will be apparent from the following detailed description when taken in conjunction with the accompanying drawings.
A support spring 28 is mounted on the base 12 and supports the trigger 22 in the open position shown in
The removable trigger 22 includes a flat portion 30 which has peripheral flanges 32, 34, 36, 38 and a central aperture 40 which has a circular flange 42. The flanges 32, 34, 36, 38, 42 and the flat portion 30 form a trough 44 which may be filled with a non-drying adhesive 46. A sheet of release paper 48 covers the non-drying adhesive 46. The central aperture 40 is in general alignment with a bait cup 50 which is formed on the base 12.
The removable trigger 22 includes a projecting plate 52. The projecting plate 52 is in general alignment with the flat portion 30. The projecting plate 52 has an end 54 with a pair of tapered portions 56, 58. The projecting plate 52 includes a pair of notched portions 60, 62 disposed near the end 54.
When the removable trigger 22 is pushed in the direction shown by the arrow 66 in
The details of construction of the base 12, jaw 14, catch mechanism 16 and the load spring 18 are well known in the prior art and therefore have not been described in detail.
The trigger support 20 is connected to the base 12 pivot 84. The flange 86 engages the end portion 88.
When a rodent attempts to escape from the removable trigger 22, the motion of the rodent is transmitted to the trigger support 20 and catch mechanism 16, which has been shown schematically in
A second embodiment of the invention 200 is shown in
A third embodiment of the invention 300 includes a removable trigger 302 which is shown in
The trigger support plate 310 is connected to the base 12 as previously described. When the removable trigger 302 is pulled in the direction shown by the arrow 320 in
The trigger support plate 310 includes a flange 326 which projects over and engages end 328 of the projecting portion 346 of the removable trigger 302.
The removable trigger 302 includes flange portions 330, 332, 334, 3346, a base portion 338, and a circular flange portion 340 which define the trough portion 304. The circular flange portion 340 defines an aperture 342. The trough portion 304 is filled with a layer of non-drying adhesive 342.
A fourth embodiment of the invention 400 is shown in
The base plate 402 includes flanges 424, 426, 428, 430 which engage and hold a removable glue board 432. The glue board 432 has a flexible cardboard member 434 and a non-drying adhesive layer 436. The edges 438, 440, 442, 444 of the non-drying adhesive layer 436 are spaced away from the edges 446, 448, 450, 452 of the cardboard member 434 leaving a border 454 which engages the flanges 424, 426, 428, 430 and which is free of adhesive.
The border 454 on the glue board 432 ensures that the glue board 432 will not adhere to the flanges 424, 426, 428, 430.
The base plate 402 includes an aperture 456. To remove the glue board 432, the bottom 458 of the glue board 432 is pressed in an upward direction by the user in the direction shown by the arrow 460 in
A fifth embodiment of the invention 500 is shown in
The foregoing specific embodiments of the present invention as set forth in the specification herein are for illustrative purposes only. Various deviations and modifications may be made within the spirit and scope of this invention, without departing from a main theme thereof.
